Well dude first off... Enjoy your suspension till youre 18.
Secondly, you are SO young! Dont NOT take AAS.
Im willing to bet that a few tweaks in your diet and training will do wonders for you!
If you are only 17, and youre already 190lbs with 8%BF, you have all the potental in the world to be as big as you want without the use of AAS.
Please heed what people here tell you...
